What chronic stress does to your body: belly fat, cravings, skin and immunity

The Short Version

Chronic stress is not just a bad mood; the experts here describe it reshaping the body from the belly to the immune system to the skin. Neuroscientist Dr. Tara Swart explains how constantly high cortisol drives stubborn belly fat, erodes immunity and pushes the brain into "low power mode" [1]. Dr. Elissa Epel shows how stress fuels cravings for comfort food, insulin resistance and abdominal fat, and how the way we respond to stress is linked to cellular aging [2]. Dr. Sara Szal and Dr. Gabor Maté connect toxic stress and trauma to autoimmune disease, especially in women [3][4], and dermatologist Dr. Teo Soleymani describes the skin as a biosensor where chronic stress shows up as faster aging, while stepping away from stress brings measurable improvement [5]. The shared conclusion is that managing stress pays off in your waistline, your immune system, your cells and your skin, not only in how you feel.

What They Said

Dr. Tara Swart: cortisol, belly fat and the brain's low power mode

Swart, an MD, PhD and neuroscientist, starts by defending cortisol. It is not all bad: it helps us wake up and dodge a speeding car, and then it should drop back to normal [1]. The problem is modern life. A constant flood of information and psychological threats keeps cortisol near the top of its range all the time [1]. Receptors in the brain read those constant high levels as an imminent threat to survival, and because we are wired, as she puts it, "in such a cave person way," the brain assumes the threat is starvation and stores extra fat in the abdomen [1].

Belly fat specifically. When Mel Robbins asked if she was saying stress causes belly fat, Swart answered: "it's not just causing fat, it's specifically causing belly fat" [1]. She offers a simple warning sign: "you may not have changed your shape and the rest of your body, but if you're noticing that your belt has become tighter, that's a sign that you could have chronic cortisol" [1]. And it is stubborn fat. People who notice it often start moving more or eating less, "but the belly fat doesn't change because the cortisol is driving the fat there regardless of your behavior in the physical world" [1]. The whole process, she says, is initiated in the brain, which is picking up on the higher cortisol [1].

A corrosive agent. Swart asks listeners to "think of this cortisol as a corrosive agent that's literally flowing through your entire brain and body" [1]. In the body, "it starts to erode your immunity," so you might notice more colds and flus, or ones that last for weeks [1]. She recalls the financial crisis, when she worked with banks and hedge funds and people told her they had had a cold for four, six or eight weeks but that everybody had it. Her response: "do you hear what you're saying that it's not normal to have a cold for six weeks? And this is cortisol" [1]. At the extreme, she says, "people were dropping dead of heart attacks on trading floors" [1]. Lowered immunity and a corroded body, in her account, "can cause everything from colds and flus to heart attacks and cancers" [1].

Low power mode. In the brain, chronic stress triggers what she calls "low power mode, like on your phone" [1]. Once the brain's receptors sense an imminent threat, it stops sending blood supply to its highest functions, "thinking creatively, thinking flexibly, solving complex problems, overriding our biases, regulating our emotions," because they don't serve pure physical survival [1]. What's left is the ability to get up, sit at your desk and look like you're doing your job even if you can't really do it. She says, "This is the reason that present-eism costs businesses more than double what absenteeism does" [1]. The brain is expensive to run: it is maybe two or three percent of body weight but uses about 20 percent of what you eat while you sleep, 25 percent while you're working, managing or running your family, and "if you're stressed, it's using 30 percent" [1].

Stress is contagious. Swart also explains that stress spreads. Among silverback gorillas, the leader's stress affects the others more than the reverse, and the same holds for a stressed boss or parent [1]. Her protection, both for your own stress and other people's, is "mostly through mindfulness activities," practices that connect brain and body such as "meditation, yoga, time in nature, journaling, gratitude," which reduce cortisol and move the autonomic nervous system from sympathetic fight-or-flight to parasympathetic, "which is rest and recover" [1]. She adds that addressing the root cause matters, rather than endlessly shielding yourself [1]. Robbins adds her own shield, telling herself "let them" be stressed: "Their stress is theirs. It doesn't have to be mine" [1].

Breaks as biology. In the same episode, Harvard stress expert Dr. Aditi Nerurkar makes a related point: "A break is not just a nice to have luxury. Your brain and your body need a break. It is a biological necessity for your brain and body to rest and recover" [1]. Productivity, she says, runs on a curve rather than a line, and most of us live on the overstressed side [1]. Mindless scrolling on a break is not neutral: "You are actively influencing your brain and your body for more stress" [1]. Instead she recommends heart-centered breathing, a short walk, stretching or her three-second stop, breathe and be reset, which pulls you out of future-focused "what if" thinking [1].

Dr. Elissa Epel: stress, cravings, belly fat and cellular aging

Epel, a UCSF professor of psychiatry and author of The Telomere Effect and The Stress Prescription, has spent her career studying how stress gets under the skin [2]. She defines stress as feeling that demands exceed our resources, and stresses that the stressor itself is not the main problem; our response is, and especially how long we keep it alive afterward [2]. Mounting a stress response and recovering is healthy; the modern problem is keeping the response running long after the event, often through our own thoughts [2]. She notes that 46 percent of adults reported feeling overwhelmed by stress in the past year, and that young adults report roughly four times the stress of adults over 65 [2]. Many people are so used to daily stress that they no longer notice it, holding tension in clenched fists and shoulders [2]. The stress response is also energetically expensive, drawing on ATP from mitochondria, which helps explain why chronic vigilance leaves people exhausted [2].

Two ways to react. Epel's research distinguishes a threat response from a challenge response to the same stressor [2]. In a threat response, people feel their survival or social standing is at risk; blood vessels constrict, cortisol rises, recovery is slow and inflammation follows [2]. In a challenge response, people think they can handle it; the heart pumps more blood, the brain gets more oxygen, problem solving improves, inflammation is lower afterward and telomeres, the protective caps on chromosomes linked to cellular aging, tend to be longer [2]. She says research by Wendy Mendes and others shows people can be nudged toward the challenge response [2]. Importantly, she does not say all stress is bad: having no stress often means not engaging with life, and short, manageable stressors can build resilience [2]. Toxic, chronic stress is what accelerates aging [2].

Why stress drives cravings. Huberman says he eats less when stressed, and Epel explains that "high sympathetic" reactors like him (and like herself, who says she lost weight writing her dissertation) tend to shut down digestion [2]. But that is not the common pattern: "most people complain about overeating or binge eating when they're emotional when they're stressed" [2]. In these people, "the stress response is driving cravings and also let's say high insulin or an insulin resistance state," which tends to go along with being overweight [2]. Stress pushes them toward "the comfort food the high fat high sugar high salt," and "with repeated bouts of stress you're just going to be gaining weight and particularly in the intra abdominal area" [2].

She explains the logic in the same survival terms Swart uses. In rat studies, stressed animals given Oreos develop binge eating and a metabolic syndrome in which their "belly fat basically expands like a cushion and that's because that's this really good immediate source of energy during stress" [2]. As she puts it, "if our body thinks we're under chronic stress we're going to store stress fat" so it can be mobilized in a second [2].

Compulsive eating. Epel describes a compulsive eating style in which people "can't feel satiated," feel they can't control their eating, don't get full and think about food a lot, and "stress kind of exacerbates that tendency" [2]. She estimates "maybe 50% of people with obesity have that," versus fewer than 20 percent of lean people, many of whom rely on strong dietary restraint [2]. The brain's opioid and reward systems are involved: her Yale colleague Rajita Sinha found that among people with obesity, "the more insulin resistant they are the more their reward center lights up during stress" [2]. Epel is careful here. Obesity, she says, "it's completely heterogeneous," and it has been a mistake to confound all obesity with food addiction; only some people have a dysregulated stress response, which is why her trials now screen for cravings [2]. A combination of naltrexone and bupropion has been used to damp down compulsive eating [2].

What helps. Epel sorts tools into three bins: top-down strategies (awareness, beliefs, mindsets), body-based strategies (exercise, breathing, movement) and changing the scene [2]. For stress eating, she trains people to check in before eating, label their emotions separately from hunger, and rate hunger from one to ten to see whether they're really hungry or bored [2]. Another skill is to "surf the urge," watching a craving rise and pass [2]. Push-ups, a walk or getting away from food all help, and so does changing the environment [2].

She is blunt about sugary drinks: "there is nothing worse than drinking sugar soda for our body" [2]. At UCSF, she and colleagues including Robert Lustig removed sugary drinks from all hospitals and campuses [2]. Two things happened: heavy soda drinkers "lost weight in the most important place," around the waist, but compulsive eaters did not benefit until they received motivational interviewing that tied their goals to things like time with grandchildren and avoiding diabetes [2]. At least 100 hospitals have since stopped selling sugary drinks [2].

The body scan and mindfulness. In a trial of pregnant women with excess weight, a program of mindful eating and stress reduction did not prevent excess weight gain, but half as many women in the mindfulness group developed impaired glucose tolerance, their babies had less obesity and fewer illnesses in their first year, and the mothers' mental health stayed better for eight years [2]. Epel also cites a study in which overweight people with strong cravings significantly reduced them with a body scan, moving attention slowly from head to toe [2]: "The body scan would significantly reduce cravings" [2].

Aging at the cellular level. Short-term meditation training dampens inflammatory gene expression and boosts telomerase, the enzyme that rebuilds telomeres, and long-term meditators have been found to have longer telomeres [2]. With Martin Picard, Epel found that mothers caring for children with autism had markedly lower mitochondrial activity than mothers of neurotypical children, and that caregivers with healthier mitochondria reported more positive emotion, especially in the evening [2]. People who can find some contentment at the end of a stressful day tend to have less depression, heart disease and early death a decade later [2]. When her team pinged caregivers in the evening, how much they were wishing things were different, and how engaged they were in the present, predicted unhappiness and shorter telomeres [2]. Her remedy for unchangeable stressors is radical acceptance, which she pictures as dropping a rope you have been pulling against a brick wall [2].

Dr. Sara Szal: stress and trauma as autoimmune triggers

Szal, a Harvard-trained physician who directs precision medicine at the Marcus Institute of Integrative Health and wrote The Autoimmune Cure, explains autoimmune disease simply: the immune system "becomes imbalanced and it starts to attack your normal tissues. You can think of it like a case of mistaken identity" [3]. The immune system is supposed to act like private security, identifying healthy tissue and attacking invaders; when it gets confused, it attacks normal tissue instead [3]. She notes that 30% of Americans have antinuclear antibodies against their own cells, which she calls a civil war in the body that saps energy [3].

Three root causes. Citing a pediatric gastroenterologist at Massachusetts General Hospital, Szal lists three requirements for autoimmunity: "Number one, genetic predisposition. Number two, leaky gut," and "number three, a trigger" [3]. The number of people with positive antinuclear antibodies has almost tripled over 25 years, which she reads as a sign that "the genetics haven't changed. It's the triggers, it's the lifestyle, it's the environment that has" [3].

Stress in the gut. Two of her root causes involve stress directly. Leaky gut, which she describes as a loss of a boundary in the body, happens when the tight junctions between gut-lining cells fail, letting viruses and foods through to provoke the immune system, 70 to 80% of which sits right there [3]. The worst offender is alcohol, but too much stress also contributes: the brain releases corticotropin-releasing hormone (CRH), which she says directly pokes holes in the gut [3]. Even hard athletic training "raises cortisol levels and it can cause leaky gut," which she sees in professional athletes she works with [3]. She had just been reading data on "how night shifts are associated with more autoimmunity," because of disrupted circadian rhythms and mitochondria [3].

Trauma as the top trigger. "The number one trigger is trauma," Szal says [3]. She was not taught much about trauma in medical school 30 years ago but kept noticing patterns in her patients: a traumatic birth, an adverse childhood experience score, sexual or physical abuse or neglect, all tracking with autoimmunity. "So trauma, toxic stress is a huge category" [3]. Hormonal shifts like pregnancy, postpartum, perimenopause and menopause are the other big category [3].

Why the past stays in the body. Szal reads the adverse childhood experiences (ACE) questionnaire and says people with elevated scores had greater risk of 45 different chronic diseases in midlife, including autoimmune disease; her own score is six, and she says every point of elevation raised the risk of autoimmunity by about 20% [3]. She explains the link through the PINE network, psychology, immune, nervous and endocrine systems, which childhood adversity dysregulates [3]. For some it shows up in the immune system, for others as cortisol problems, for others as nervous system dysregulation such as low heart rate variability or chronic anxiety [3]. Many people believe they have dealt with their past, but "there's a way that ACEs live on in the body. Even if you think you've already cognitively processed it" [3]. People often don't connect it to their high blood sugar, multiple divorces or conflict at work [3]. Robbins sums it up in the conversation: with stored adversity "you're always bracing and you're always still feeling like there's some level of threat," so the body's healthy internal boundaries slowly wear down [3].

Why women. Autoimmune diseases affect "Four times more women than men," Szal says [3]. Biology, like the X chromosome, is "necessary, but it's not sufficient" to explain the dramatic rise [3]. The more concerning factors are socially constructed: women experience more stress and more trauma, and earlier, and when exposed to the same trauma have higher rates of PTSD [3]. Her summary: "It's a health hazard to be female in our culture" [3].

The cortisol irony. Szal points out that standard treatment for psoriasis is a steroid cream: "The steroid is like cortisol. It's like the stress hormone that you're sticking on your scalp. No one's thinking about your gut" [3].

What to do. Her three steps are to get tested, try a three-week elimination of gluten, dairy, sugar and alcohol, and track and address triggers, including stress and trauma [3]. She calls breath "the most underutilized health tool in the world," explaining that shallow chest breathing signals to the brain and immune system that you aren't safe, and she leads Robbins through slow breathing of about five and a half seconds in and out, saying even three breaths start to change physiology [3]. Because "you can't think your way out of trauma," she recommends creating safety in the body through breathing, meditation, yoga and embodiment [3]. She stresses that lifestyle medicine is added to mainstream care, not substituted for it [3].

Dr. Gabor Maté: the body says no

Maté, a physician with decades in family and palliative care, supplies the psychological side of the autoimmune picture [4]. About 80% of people with autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, lupus, ulcerative colitis and Crohn's are women [4]. Because he knew many patients before they got sick, he noticed four recurring traits: putting other people's emotional needs ahead of their own, identifying with duty and role rather than the self, being very nice and repressing healthy anger, and believing they are responsible for how others feel [4]. Those beliefs mean never saying no, absorbing everyone's stress and exhausting the body [4].

Chronic, quiet stress. Maté's key distinction is between the dramatic stress doctors recognize and the chronic kind they miss. "Doctors know that in cases of acute stress, that can flare up a disease. That's clear," he says, "But they don't recognize those emotional patterns that I'm talking about, which stress people chronically, but in less dramatic ways" [4]. He asks: "what's it like to always have to repress your anger to be pleasing other people" [4]. His summary is stark: "You've abandoned yourself, and now your body function is abandoning you" [4].

One system. He explains this through psychoneuroimmunology, the science showing that the nervous, hormonal, immune and emotional systems are one interconnected system [4]. Healthy anger is a boundary defense, and so is the immune system; suppress one and you suppress the other, so the body turns against itself [4]. His answer to why women: "It's not a gender issue. It's a cultural issue," because the culture programs women to care for everyone else and never be angry [4]. He adds that minority women face even higher rates, and that Indigenous women in Canada have six times the rate of rheumatoid arthritis [4].

The steroid irony. Maté makes the same observation as Szal, more pointedly. "Typically for these conditions, we give cortisol," he says: steroid cream for inflamed skin, cortisol for inflamed intestines and for multiple sclerosis [4]. "But we never ask ourselves, gosh, we're getting stress hormones to people. Is it possible that stress may have something to do with their condition?" [4]

Stress and the developing brain. Maté also traces stress back to its earliest effects. "The number of dopamine receptors in the child is affected by stress on the mother already in pregnancy," he says, and isolating mice lowers their dopamine receptors while companionship raises them: "the brain is a social organ" [4]. He sees addiction the same way, as an attempt to soothe pain, calling it "a perfectly normal response to abnormal circumstances" [4]. He points to Vietnam veterans who used opioids overseas but were not addicted after coming home to supportive environments, and to rats in good conditions that could not be made addicted no matter how much opioid they received [4].

The good news. "If you change these patterns, you can actually significantly affect the course of your illness," Maté says, adding that he knows many examples [4]. His exercise is a series of questions: where do you have difficulty saying no, what is the impact on you, what belief sits behind it, how did you learn it, and who would you be without it [4]. Then a sixth: "Where are you not saying yes?" [4] Much of what helps is free: talks, library books, meditation, time in nature, exercise and attention to food [4].

Dr. Teo Soleymani: the skin as a stress biosensor

Soleymani, a double-board-certified dermatologist and skin cancer surgeon, adds the most visible organ to the picture [5]. The skin's surface replaces itself about every 28 days, and most of its biological activity, blood vessels, nerves, hair follicles, oil and sweat glands, lives in the dermis [5].

Acute versus chronic stress. Acute stress triggers a fight-or-flight response that constricts skin blood vessels, which is why stressed people look pale or gaunt, and it can cause hair shedding [5]. He sees students losing clumps of hair around finals week, which grows back months later [5]. Chronic stress works mainly through cortisol, which breaks down collagen and elastin and thins vessel walls, accelerating visible aging [5]. He notes studies of presidents who appeared to age much faster than matched controls over four years [5].

It reverses. The encouraging flip side, he says, is that when people move away from stress there are "actual quantifiable improvements in skin health," which is why people seem to glow after a vacation [5]. He calls skin, hair and nails a biosensor: the body sheds what it doesn't need when it is fighting something else [5].

The stress-adjacent habits. Soleymani's other advice overlaps with the habits stress tends to bring. Nicotine from smoking and vaping causes measurable chronic vasoconstriction in the skin, so smokers age faster and heal poorly: "if you want to look younger I would refrain from nicotine use" [5]. Alcohol is "generally thought to be a net net negative" for skin, drying it, triggering extra oil and breakouts, and bringing poorer sleep, hydration and diet [5]. Stress is also a trigger for rosacea flushing, alongside UV, spicy food, hot drinks and alcohol [5]. On diet, he describes a strong gut-skin connection: controlling gut dysregulation and eating an anti-inflammatory diet measurably reduce psoriasis, eczema and acne, and he notes that a few days of sugar reliably makes him break out [5].

The immune link. Soleymani's discussion of psoriasis and vitiligo connects directly to Szal and Maté. Psoriasis, which he has himself, was treated for a century as excess skin growth before research showed it is driven by an overactive skin immune system [5]. Vitiligo is an autoimmune disease that destroys pigment cells [5]. Szal lists psoriasis among autoimmune conditions whose gut and trigger roots go unaddressed when patients just get a steroid cream [3], and Maté includes some forms of psoriasis and eczema in his list [4]. Soleymani also points out that skin cancer risk depends heavily on the immune system: transplant patients on immune suppression in the early 1990s died of metastatic skin cancer at high rates despite strict sun protection [5].

Where They Agree, and Where They Don't

Agreement. All five sources describe chronic stress as a whole-body state, not a feeling. Swart and Epel both describe the same survival logic behind belly fat: the brain reads chronic stress as a threat and stores abdominal fat as ready energy [1][2]. Swart, Szal and Maté all tie chronic stress or trauma to immune changes, whether lingering colds [1], autoantibodies and leaky gut [3], or the immune system turning on the body [4]. Soleymani sees the same cortisol at work in the skin, breaking down collagen and elastin [5].

They also agree it is reversible, at least in part. Swart says mindfulness practices move the nervous system into rest and recover [1]; Epel shows that mindfulness and meditation affect glucose tolerance, cravings and telomerase [2]; Szal says small changes add up as the body gets the message that it is safe [3]; Maté says changing emotional patterns can significantly affect the course of illness [4]; and Soleymani sees quantifiable skin improvements when people step away from stress [5].

Szal and Maté independently make the same pointed observation: medicine treats these conditions with cortisol, a stress hormone, while rarely asking whether stress helped cause them [3][4].

Differences and nuances.

Is stress always bad? Swart emphasizes cortisol as corrosive when chronic, while accepting it is useful in short bursts [1]. Epel goes further in defending stress: too little stress is not ideal, short manageable stressors build resilience, and the same stressor can produce a healthy challenge response or a harmful threat response depending on how you see it [2]. She is the only source who stresses that your interpretation can change the biology.

Is belly fat inevitable under stress? Swart describes cortisol driving belly fat "regardless of your behavior" [1]. Epel's picture is more varied: some people, like Huberman and herself, lose weight under stress, and the stress-eating pattern belongs mainly to a compulsive-eating subgroup [2]. She warns that obesity is heterogeneous and should not all be lumped together [2]. And her soda study showed that changing the environment did reduce waist weight in heavy drinkers [2], which suggests behavior still matters.

Where does the harmful stress come from? Swart points to modern information overload and psychological threats [1]. Epel emphasizes our own thoughts and rumination keeping stress alive [2]. Szal and Maté look further back, to childhood adversity, trauma and culturally learned patterns like people-pleasing [3][4]. Soleymani focuses on present-day stress and the habits that come with it [5]. These are complementary, but they point to different fixes: breaks and mindfulness, reappraisal and acceptance, or trauma work and learning to say no.

How strong is the evidence? The sources vary. Epel cites controlled trials, including a years-long study of pregnant women [2]. Szal cites the ACE research and a randomized trial of elimination diets in rheumatoid arthritis [3]. Maté draws heavily on his clinical observations as a physician who knew patients before they got sick [4]. Swart's banking anecdotes about six-week colds are illustrations rather than studies [1]. Readers should weight the claims accordingly.

Why It Works

The sources describe several connected mechanisms.

Cortisol as a survival signal gone chronic. Cortisol is meant to rise and fall [1]. When it stays high, brain receptors interpret it as an imminent threat [1], and the body prepares for starvation by storing fat in the abdomen as quick energy [1][2]. Epel adds that the stress response can drive insulin resistance and reward-driven cravings for high-fat, high-sugar, high-salt food, reinforcing the cycle [2].

The brain rations its fuel. Under stress the brain uses more fuel, about 30 percent of what you eat versus 20 to 25 percent otherwise, and diverts blood away from creativity, problem solving, bias control and emotional regulation [1]. That is why stressed people function worse, not just feel worse [1].

Threat versus challenge physiology. In a threat response, blood vessels constrict, cortisol rises, recovery is slow and inflammation follows; in a challenge response, blood flow to the brain improves and inflammation is lower [2]. These patterns are linked to telomere length [2], and energy for the stress response comes from mitochondria, whose health tracks with caregivers' evening mood [2].

Stress opens the gut. Stress hormone signaling (CRH) and high cortisol from intense training increase gut permeability, exposing the large share of the immune system that sits in the gut to things that provoke it [3].

One interconnected system. Szal's PINE network and Maté's psychoneuroimmunology describe the same idea: psychology, nerves, hormones and immunity are one system, so early adversity or chronic emotional suppression can dysregulate immunity [3][4]. Maté adds that anger and immunity are both boundary defenses, so suppressing one weakens the other [4].

Cortisol in the skin. Acute stress constricts skin blood vessels; chronic cortisol breaks down collagen and elastin and thins vessel walls [5]. Nicotine's vasoconstriction and alcohol's drying effect compound it [5].

Signals of safety. On the repair side, practices that connect brain and body shift the nervous system from sympathetic to parasympathetic [1]. Slow breathing signals safety to the brain and immune system [3], and body scans may reduce cravings by refocusing attention inward [2].

Where It Applies, and Where It Doesn't

Where it applies.

• Stubborn belly fat despite diet and exercise. Swart's belt-tightening sign [1] and Epel's stress-eating pattern [2] describe people for whom stress, not just calories, may be part of the problem.
• Frequent or lingering infections. Swart's colds that last six weeks [1].
• Autoimmune conditions and unexplained fatigue, joint pain or flares, especially in women and in people with a history of childhood adversity [3][4]. Szal notes perimenopause and menopause, roughly ages 40 to 55, are a major spike [3].
• Chronic caregivers and people in unchangeable situations, where Epel's radical acceptance and evening mood findings apply [2].
• Skin aging, hair shedding and stress-triggered conditions like rosacea flushing [5].

Where to be careful.

• Stress is rarely the only cause. Szal is explicit that autoimmunity also requires genetic predisposition and involves leaky gut and other triggers such as hormones and alcohol [3]. Soleymani stresses genetics and the immune system in skin cancer [5]. Epel says obesity is heterogeneous [2].
• Not everyone responds the same way. Some people lose weight under stress [2], and some have bigger threat responses because of inherited tendencies or early trauma, for which Epel advises self-compassion [2].
• Some stress is good. Epel warns that no stress at all is linked to worse cognitive health, and that manageable challenges build resilience [2]. The goal is recovery, not avoiding all stress.
• Lifestyle doesn't replace medicine. Szal says lifestyle medicine is layered onto mainstream care, and some conditions, like type 1 diabetes once the insulin-producing cells are destroyed, require medication [3]. Maté is not against medication either [4].
• Clinical observations are not proof of cause. Maté's four traits come from his clinical experience [4], and some of Swart's examples are anecdotes [1].

If you have persistent symptoms, an autoimmune condition, stubborn weight changes or skin problems, talk to a doctor before making major changes, and treat these stress tools as additions to medical care rather than replacements.

What To Do With It

1. Watch for the body's stress signals. A tightening belt without other shape changes [1], colds that won't go away [1], hair shedding after a stressful stretch [5] and a flaring skin or autoimmune condition [3][5] can all be signs that stress is chronic, not just emotional.
2. Take real breaks, and don't spend them scrolling. Nerurkar calls breaks a biological necessity and says scrolling primes your body for more stress; use a short walk, stretching, heart-centered breathing or a three-second stop-breathe-be reset instead [1].
3. Do a daily mind-body practice. Swart recommends meditation, yoga, time in nature, journaling or gratitude to lower cortisol [1]; Epel says we should all do some form of body scan or mind-body practice [2].
4. Breathe slowly. Try Szal's slow breathing, about five and a half seconds in and five and a half seconds out; she says even three breaths start to change physiology [3].
5. Reframe the stress in front of you. Use Epel's stress shields: list your resources, recall past successes, think of someone who supports you, and ask whether it will matter in five or ten years, so the same stressor produces a challenge response instead of a threat response [2].
6. Break the stress-eating loop. Before eating, label your emotion, rate your hunger from one to ten, and practice surfing the urge; remove sugary drinks from your home and workplace [2].
7. Accept what you can't change. For unchangeable stressors, practice dropping the rope and notice how much of your evening goes to wishing things were different [2].
8. Find where you can't say no. Work through Maté's questions weekly: where you struggle to say no, what it costs you, the belief behind it, where you learned it, who you'd be without it, and where you are not saying yes [4].
9. Address the gut and triggers. If autoimmunity is a concern, ask about testing, consider Szal's three-week elimination of gluten, dairy, sugar and alcohol with your clinician, and look honestly at stress, night shifts and past trauma as triggers [3].
10. Protect your skin's recovery. Cut nicotine, limit alcohol, eat a high-protein anti-inflammatory diet, and take real time away from stress; Soleymani says the improvements after a vacation are measurable [5].
